Can anyone speak to this issue so that I can work? N4 sometimes gives message to authorize plugin, even though I've been using it for months (REAPER 64, Win10). When it doesn't give that message, it never progresses beyond "Loading" and you cannot open the Finder. No response yet from Support and I am losing valuable working time for an expensive plugin with no provided documentation. Has anyone experienced this and have a fix to suggest? Have already tried reinstalling from Aquarius
